Music and Social Interaction in the Treatment of Post-Stroke Aphasia

Cerebrovascular disease is a leading cause of disability and death worldwide, with about one third of stroke survivors initially suffering from communication disorders, including aphasia. Symptoms in aphasia vary from person to person, ranging from repeated failures in verbal expression to comprehension deficits that may occur in both the spoken and written modality. The current work synthesizes almost a decade of research on aphasia following left-hemispheric stroke in individuals with preserved right-hemispheric function: musical skills and formulaic expressions embedded in social interaction. Moving beyond the traditional scope of clinical linguistics, this work argues that preserved right-hemispheric function not only provides valuable resources in speech-language therapy, but also a possible foundation for psychotherapy in individuals with post-stroke aphasia and concomitant depression. An integrative summary introduces key developments in a line of research spanning from 2013 to 2021, to conclude with an outlook on forthcoming contributions and a commentary on the underlying conceptual framework. Each separate piece of research has been published previously in peer-reviewed journals. Here, the selected studies are assembled in an interdisciplinary context at the intersection of clinical neuroscience, speech-language pathology, and psychotherapy.
